<3>To prevent against shift of the CCD unit optical axis, mark the CCD
unit base as shown below.
Note: This procedure must be executed also when the CCD unit is
replaced.
<4>Loosen the CCD unit fixing screws.
Note:Never loosen the screws marked with X.
If any one of these screws is loosened, the position and the angle
of the CCD unit base may be changed to cause a problem, which
cannot be adjusted in the market. In that case, the whole scanner
cannot be adjusted in the market. In that case, the whole scanner
unit must be replaced.
<5>Slide the CCD unit in the arrow direction (CCD sub scanning
direction) to change the installing position.
When the copy image is longer than the original scale, shift the
CCD unit in the direction B. When the copy image is shorter than
CCD unit in the direction B. When the copy image is shorter than
the original scale, shift the CCD unit in the direction A.
One scale of mark-off line corresponds to 0.2%.
At that time, fix the CCD unit so that it is in parallel with the scale on
the front and the rear side of the CCD unit base.
Note:Fix the CCD unit so that it is in parallel with the line marked in
procedure <3>.
<6>Make a copy and check the copy magnification ratio again.
If the copy magnification ratio is not in the range of 100 ± 1%, repeat
the procedures of <3> - <5> until the condition is satisfied.
